Abstract
Techniques of designing an antenna array with antenna units controlled electronically are described. Through controlling the combination of the reflectors in each of the antenna units, a desired antenna pattern is formed, adapting to the environment, and providing reliable and efficient links between two transceivers. According to one aspect of the present invention, a switch (e.g., a diode) is used to couple two reflectors. The diode is controlled to be on or off so that the reflectors are conductively integrated or separated.
